A major telecommunications firm invented a new locating technology that it wanted to combine with a personal cellular emergency device. The goals were to make a device that could be activated easily by someone in distress, but difficult to activate accidentally. A wide variety of mock-ups and sketches were presented.

Shown above are computer-generated renderings of three of the proposed designs. The upper two designs use a translucent cover to protect the buttons. The flip-open cover has an antennae made of ion-deposited metal. The design on the left is activated by pinching the two membrane switches. This concept proved to be a very effective technique to prevent false alarms while allowing easy activation even with limited visibility, dexterity, strength or cognitive ability.
